Does anyone have any ideas?
It sounds like it’s not getting power.
Can the information on the drive be recovered?
Not unless the power problem is resolved. Check the drive’s contacts, make sure they aren’t bent or oxidized. Try different USB ports, USB 2.x vs USB 3.x. Try more computers. If the files are important find a local repair shop and see if they can check the contacts. Formatting and recovery apps won’t fix this problem.
SanDisk will replace the drive but not the files.
